Does the mother of a deceased married daughter who has children inherit from her?

This woman's mother receives one-sixth of the inheritance, based on the Almighty's saying: "And for his parents, each of them the sixth of what he left if he had a child" (An-Nisa: 11). We alert the questioner that inheritance matters are serious and complex, and a mere fatwa is not sufficient. Rather, they must be referred to the Sharia courts for investigation; there might be an heir, bequests, debts, or other rights that take precedence over the rights of the heirs. Therefore, the inheritance should not be divided without consulting the Sharia courts.
